Anti-stranger mode not working


Aug 30, 2012
I'm running 2.3.30 on a G2 (Desire Z), and I'm not sure if this is version specific or platform specific so I'm posting here.

I have run MIUI in the past but tried a few other ROMs and now I'm back to MIUI (it's the best!). For some reason in this version I cannot get anti-stranger mode to work. I didn't have any trouble with past versions. I have the firewall enabled and anti-stranger enabled, but unknown calls still come through - is there something else I need to check?
